Regarding repatriation of funds first. We bought a plot of land in 1999 and built a villa. I realise that this is a complicated way to go about things in a foreign land - but at the time we had been looking to buy over there for some time and the opportunity came up to buy from a large, very reputable company (CGI) All the funds used for the purchase and the subsequent construction were transferred bank to bank from the UK, and fully traceable. We are both British citizens, although one of us is of Moroccan origin, but not born in Morocco.
We are not resident in Morocco, and have never really had much benefit from having the villa over there, it was really a bit of a waste (due mainly to personal circumstances) so last year we decided to sell it.

Although paying for a proportion of a property 'on the black' is widespread in Morocco, we put the villa in the hands of a local Notaire (solicitor), who agreed an asking price with us, and after a few months telephoned us with an offer, which we accepted. This was last December. We went to Morocco mid-March to finalise the sale. We declared every penny of the sale price. The purchasers were buying with a large bank loan and the Notaire said that the whole amount had to be declared in that case. We then found out that all the running around to pay the various charges and taxes due on the sale would have to be done by ourselves - and the Notaire would with-hold a large chunk of the funds until we provided all the 'Quittus' to prove we had paid all the taxes due (TPI, TVA, Tax Urbaine etc) This was fair enough - we knew we would have taxes to pay. We spent 2 months running around from a to b to deal with the calculation and payment of the taxes due. We paid the whole of the TPI (capital gains tax equivalent) due on the sale price, only to find to our horror that the Tax office decided that the house was worth 550000 dirhams MORE than we had sold it for, and presented us with a bill for a further 140000 dirhams on top of the 85000 dirhams TPI we had already paid! PLUS if we didn't pay up within a month there would be a majoration added on top every month until it was paid. It seems that they know many sellers do not declare the whole amount, so they penalise everyone regardless of whether they are honest or not! They are holding us to ransom, as until this amount is paid, the Notaire will not release the remainder of the purchase funds into our accounts.
As for the transfer of funds out of the country when you sell - well, unless you want to do it on the black market and carry thousands and thousands of euros in cash in a suitcase, you have to go through the `Office de Change'. The transfer can be done just the once. As one of us is a foreigner resident abroad, one half of the purchase funds has to go into a 'Compte en Dirhams convertibles' - and can only be transferred out of Morocco at 25% per year over 4 years. The other 50% in theory can be transferred as the other one of us is an MRE (Moroccan resident a l'Etranger) We have been getting the transfer dossier together for another trip back to Morocco later in the year, when hopefully the taxes will have been sorted out and paid and we have the necessary 'Quittus' to allow us to have our OWN money from the sale! In any event - if we end up with the original amount we invested almost 10 years ago, after the taxman has finished with us, we will consider ourseves lucky.
Just another point about Tamesna (near Rabat) I have seen apartments advertised there off-plan by several UK websites. We went to look at what seemed like a very attractive development, until, whilst in Morocco, we read a newspaper article stating that the Government has agreed to build a large number of 'social housing' flats on that development - where they re-house families moved out from the shanty towns in the centre of the city. When we pointed out the article to one of the UK companies selling on that development they didn't want to know, even when we offered to scan and email them the newspaper article.
We have returned from Morocco traumatised and now wish only to warn prospective buyers of what to be aware of - as neither the selling agents nor the Notaires handling the purchase seem to be prepared to point out the pros and cons honestly. It takes 2 minutes to transfer your money to Morocco but getting it back out again is an entirely different kettle of fish. Imagine, if you are a retired married couple (and we won't yet go into the ins and outs of the succession laws over there!!) and one of you sadly dies, the hell that the remaining partner is going to have to deal with alone in that country should be more than enough to make anyone seriously reconsider their decision to buy.
